Question: What Happens When Two Magnets Are Forced Together?

What happens when you put 2 magnets together?

When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up.

Unlike-poles attract: When a north pole and south pole point together, the arrows point in the SAME direction so the field lines can join up and the magnets pull together (attract)..

Does magnet size affect strength?

Does the size of a magnet affect its strength? The short answer is yes, but only because the size of a magnet means that there are proportionally more domains that can align and produce a stronger magnetic field than a smaller piece of the same material.

How can I make my fridge magnet stronger?

Rub a heavy-duty, strong magnet against the weaker magnet for about two or three minutes. Strong magnets work to “partially realign the magnetic domains of a weaker magnet,” according to the website Luminal Tech, and will therefore make the weaker magnet stronger.

Can a magnet that has lost its strength be re magnetized?

A magnet can be re-magnetized by rubbing a neodymium pole, for example, against the opposite pole of the old magnet, thus repeating with the other side and achieving the desired effect. … After this process, any magnet that has lost its magnetic properties can become fully functional again.

What shape of magnet is strongest?

horseshoe shapeThe strongest part of a magnet is concentrated at the poles. That is why a horseshoe shape is considered the strongest and can be very useful to create if you want to lift heavy objects or want to make a bar magnet stronger.

Which magnets are stronger?

Neodymium magnets, invented in the 1980s, are the strongest and most affordable type of rare-earth magnet. They are made of an alloy of neodymium, iron, and boron (Nd2Fe14B), sometimes abbreviated as NIB.

Do stronger magnets produce more electricity?

You will get a stronger EMF if you have a stronger magnetic field or make the magnetic field change more quickly because you will have greater flux which will generate greater force on the electrons. … Since electric power is just EMF x current, you also get a bigger power this way.

How can you increase the strength of a magnet?

The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage. You can make a temporary magnet by stroking a piece of iron or steel (such as a needle) along a permanent magnet.
